Subject: [PATCH v2 8/8] binder: add delivered_freeze to debugfs output
Date: Thu, 26 Sep 2024 23:36:19 +0000	[thread overview]
Message-ID: <20240926233632.821189-9-cmllamas@google.com> (raw)
In-Reply-To: <20240926233632.821189-1-cmllamas@google.com>

Add the pending proc->delivered_freeze work to the debugfs output. This
information was omitted in the original implementation of the freeze
notification and can be valuable for debugging issues.

Fixes: d579b04a52a1 ("binder: frozen notification")
Cc: stable@vger.kernel.org
Signed-off-by: Carlos Llamas <cmllamas@google.com>
